The specific objectives of the project were to: Acquire high quality data within the logistical, time and cost constraints of the project; Acquire acoustic and geophysical data capable of describing broadscale seabed habitats and potential historic environment assets within the region, and so develop the understanding of the physical processes that influence the regional seabed, historic environment and its faunal communities; Acquire seabed imagery to describe the types of seabed habitats and epifauna that exist within the region and enable the future interpretation of acoustic and geophysical data; Acquire seabed grab samples to describe the seabed, and faunal community’s habitats, in the region and enable the future interpretation of acoustic and geophysical data; Acquire scientific beam trawl samples to describe the epifaunal communities; Acquire data capable of determining the location and significance of rare or regionally unique habitats or those that might be considered for protection under the terms of national conservation legislation; Acquire data capable of determining the significance of habitats and benthic species identified in maintaining the health of higher tropic levels of regional marine communities; Acquire geophysical, geological and biological data to support the integrated management of offshore resources in the region and to provide a better basis for marine spatial planning.

This is approximately 54% of the original programme. Data quality is generally very good or good. There were few instrument malfunctions. Survey operations invariably ceased before data quality or personnel safety became compromised. In addition to the remote sensing programme, 70 sites were sampled for geological and environmental purposes and seabed photographs were collected. The positions of a number of these pre-selected sites were moved due to difficulties with vessel access. Beam trawls were successfully completed at 30 stations. https://www.marinedataexchange.co.uk/details/1608/summary A link to the web service or dataset. https://www.marinedataexchange.co.uk A link to the general host site.
